Abstract

L’invention concerne une turbomachine (10) comprenant une hélice (12), un arbre porte-hélice (13) portant l’hélice (12), une machine électrique tournante (19), présentant au moins une première configuration dans laquelle elle est couplée mécaniquement à l’arbre porte hélice (13), et une pompe à huile moteur (21) alimentant un circuit de lubrification (20) de la turbomachine (10). La machine électrique tournante (19) dans la première configuration est couplée mécaniquement à la pompe à huile moteur (21) de telle manière que la machine électrique tournante (19) entraîne en outre la pompe à huile moteur (21) lorsqu’elle alimentée en courant. L’invention concerne en outre un aéronef comprenant une telle turbomachine (10). Figure pour l’abrégé : figure 2The invention relates to a turbomachine (10) comprising a propeller (12), a propeller shaft (13) carrying the propeller (12), a rotating electric machine (19), having at least a first configuration in which it is mechanically coupled to the propeller shaft (13), and an engine oil pump (21) supplying a lubrication circuit (20) of the turbomachine (10). The rotating electrical machine (19) in the first configuration is mechanically coupled to the engine oil pump (21) such that the rotating electrical machine (19) additionally drives the engine oil pump (21) when supplied with running. The invention further relates to an aircraft comprising such a turbomachine (10). Figure for abstract: figure 2
